SB5101 Problems?

Hello All,

I am coming here today because I am having problems with my Cable Modem service with my ISP (Amnet) in Costa Rica. I have called them and they continue to tell me it's my hardware.

Should my hardware be faulty then no problem, I'll replace it.

My network is setup as such:

SB5101 -> DIR-825 (router) -> SR2016T (switch) -> PC (wired)

So the symptoms are, dropped packets, slow connections, instability, dropped skype calls, etc.

This morning for example I got up and I didn't have internet. I had to release and renew my IP (static) to get it to work again.

I have some errors in the modem log and i've included that below as well as the signals. I have also noticed my modem in different frequencies. Is it normal that it changes? Also I have had my modem loose it's frequency requiring a 'restore to default settings'

Downstream
Frequency: 585000000 Hz
Signal To Noise Ratio: 34.3 dB
Power Level: -5.7 dBmV

Upstream
Channel ID: 2
Frequency: 30000000 Hz
Power: 36.0 dBmV

Re: SB5101 Problems?

Your upstream power is a little low. I'd call it in to your isp. Let them know of intermitten connection.
